Solar Wire Gauge Calculator
Solar Wire Gauge Calculator . Load_current = fuse_size/1.25 (it is generally accepted that a fuse must be at minimum 125% the size of the load current); = electrical efficiency of the system. How to choose the right solar wire size RENVU from www.renvu.com A properly designed camper solar array should always be able to use 10 gauge wire for all wires between the array and the charge controller, and here is why… even if the calculator recommends a smaller wire, like 16 gauge… 10 gauge wire is simply more durable from a physical standpoint (think; Voltage at the end of the circuit (after current has passed through the wire and voltage drop has occurred). = length of the line in meters.
